“Although a claim term that does not include the word “means” is presumed not to invoke a means-plus-function analysis, that presumption may be overcome if the limitation does not “recite sufficiently definite structure” or recites a “function without reciting sufficient structure for performing that function.” Williamson v. Citrix Online, LLC, 792 F.3d 2 Section 4(c) of the Leahy-Smith America Invents Act (“AIA”) redesignated 35 U.S.C. § 112, ¶ 6, as 35 U.S.C. § 112(f). Pub. L. No. 112- 29, 125 Stat. 284, 296 (2011). Because the ’703 patent has a filing date before September 16, 2012 (effective date of § 4(c)), we refer to the pre-AIA version of § 112. 1339, 1349 (Fed. Cir. 2015). Petitioner’s expert, Russell J. Hamilton, Ph.D., testifies that “the term ‘logic’ would not be recognized by one of ordinary skill in the art as providing sufficiently definite structure for performing the claimed functions,” and that “[l]ogic can be implemented in software, in hardware, and in combinations of hardware and software.” Ex. 1021 ¶ 122. The parties provide sufficient reasoning to overcome the presumption against a means-plus-function construction, and we accordingly construe “first logic” and “second logic” in accordance with 35 U.S.C. § 112 ¶ 6.” slip op. at 9

“untenable because its broad identification only of “computer software and/or computer hardware” as structure for performing the recited function is too generic. The law regarding construction of means-plus-function limitations as applied to computer-implemented elements is well-established: For computer-implemented means-plus-function claims where the disclosed structure is a computer programmed to implement an algorithm, “the disclosed structure is not the general purpose computer, but rather the special purpose computer programmed to perform the disclosed algorithm.” . . . This court permits a patentee to express that algorithm in any understandable terms including as a mathematical formula, in prose, . . . , or as a flow chart, or in any other manner that provides sufficient structure. Finisar Corp. v. DirecTV Group, Inc., 523 F.3d 1323, 1340 (Fed. Cir. 2008) (citations omitted). Patent Owner’s proposed construction is superior because it identifies the algorithm through explicit reference to the flow chart of Figure 4 and related disclosure in the Specification. Patent Owner’s position is supported by testimony of its expert, Sasa Mutic, Ph.D., who refers to those disclosures in opining that “the [’703] patent describes a process of steps for obtaining the result of properly positioning a patient to begin a treatment” and that “Fig. 4 of the [’703] patent provides a flowchart of a process for use of an embodiment of the invention.” Ex. 2012 ¶ 69. Petitioner takes the position that the ultimate scope of the corresponding algorithm “does not matter” because Petitioner contends that the challenged claims are unpatentable even under Patent Owner’s proposed construction. Pet. Reply 315, 3. Nevertheless, Petitioner attacks Patent Owner’s proposed construction as “implicitly adopt[ing]” two “additional but unreasonable limitations.” Id. First, Petitioner contends that “the claims do not require the performance of the function of the second logic to be fully automated and instead permit human interaction with the second logic.” Id. Second, Petitioner contends that blocks 520 (“Position Patient”), 525 (“Register Treatment Image Data with Simulator/Reference Image Data and Reposition Patient”), and 530 (“Position Clinical Treatment Machine”) of Figure 4 “need not be performed in their entirety by logic so long as the second logic is used for some step in each block.” Id. at 4. We find no inconsistency in these positions with Patent Owner’s proposed construction. In light of the foregoing considerations, we adopt Patent Owner’s proposed construction.” slip op. at 14

“Petitioner contends that the claims canceled in IPR2016-00341 “were directed to methods that recited the function performed by the second logic,” and that “Patent Owner is now estopped from arguing the subject matter of the same scope is patentable.” Pet. Reply 315, 1. Petitioner cites no authority to support this position, which improperly focuses on only one limitation of the claims, divorced from the claims’ other limitations. We reject Petitioner’s contention because the method claims canceled in IPR2016-00341 do not constitute “subject matter of the same scope” as the apparatus claims challenged in these proceedings.” slip op. at 16
- Skill levelSkill level petitioner adoptedDecided for petitioner
“skill in the art relevant to the ’703 patent “would be a person with a graduate degree (MS or PhD) in medical physics or a related field (e.g. Physics, Engineering) and three years of experience in radiation oncology beyond the completion date of their degree.” Ex. 1021 ¶ 17. Patent Owner’s expert, Dr. Mutic, expresses a level of ordinary skill that is generally similar to Petitioner’s expert, but accounts for the possibility of a medical education instead of a medical-physics education: [A] person of ordinary skill in the art . . . would be a medical physicist with a Ph.D. (or similar advanced degree) in physics, medical physics, or a related field, and two or more years of experience in radiation oncology physics and image processing/computer programming related to radiation oncology applications. Alternatively, one of ordinary skill in the art might have an M.D. degree in the same relevant fields and two or more years of practical experience with image processing and the use of computer systems that is related to medical applications. Ex. 2012 ¶ 36. The similarity in the experts’ opinions is reinforced by Dr. Mutic’s assertion that he has “considered Dr. Hamilton’s definition of the level of ordinary skill in the art and determined that it does not differ from [his] own expressions of this concept in any way that is relevant to the opinions” he expresses in his Declaration. Id. ¶ 38. Based on the expert testimony in the record, we agree with and adopt the level of skill expressed by Dr. Hamilton.” slip op. at 17
